FLY-BRUSH FOR moons.

SPECIFICATION forming part of Letters Patent No. 770,906, datedSeptember 27, 1904. Application filed May 31, 1904. Serial No. 210,621.(No model.)

To It, whom, 712? puny concern.-

Be it known that I, HIRAM H. HOYT, a citizen of-the United States,residing at Clearwater, in the county of Antelope and State of Nebraska,have invented certain new and useful Improvements in Fly Brushes forDoors; and I do declare the following to be a full, clear, and exactdescription of the invention, such as 'will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in fly-brushes for driving fliesfrom screen-doors.

The object of my invention is to provide a device of this characterwhich may be readily applied to a screen-door, so that when the saiddoor is opened or closed the brushes will be agitated, therebyfrightening away any flies which may be on the door.

A further object is to provide a device of this character which will besimple, eflicient, and inexpensive and well adapted for the purposes forwhich it is designed.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawing is shown a side elevation of a screen-doorhaving applied thereto the improved fly-brush.

Referring more particularly to the drawing, 1 represents a screen-doorwhich maybe of the usual or any approved construction. On thefront orouter side of said door is journaled a vertically-disposed rod or shaft2. Said shaft is pivotally connected to said door by means of screw-eyes3, one of which is arranged in the upper cross-bar 4 of the door and theother in the intermediate cross-bar 5. On the upper end of said shaft 2is fixed a pulley 6. To the door-frame adjacent to the top of saidscreen-door is secured one end of an operating-cord 7, said cord passingaround the pulley 6 and from thence under a pulley 8, secured to saiddoor-frame, and from said pulley the cord passes around a pulley 9,mounted on a stud-bolt 10, which projects from the door-frame or wallnear the upper corner of said door. The cord 7 then passes back towardthe inner or hinged side of the door across the top of said door-frame,where it passes over a guide-pulley 12, and from thence extendsdownwardly and is connected at its lower end to a weight 13. In theshaft 2 are formed oppositely-disposed cranks 1 1 and 15. To the saidcranks 14 and 15 are respectively connected pitman-rods 16 and 17.Midway between the shaft 2 and the front edge of the door is arranged avertically-disposed rod or shaft 18, the upper and lower ends of whichare bent laterally at right angles to said rod, thereby formingcrank-arms 19, the ends of said arms being bent upwardly and downwardlyto form trunnions, which are adapted to engage screw-eyes 20, which arescrewed into the upper and lower cross-bars of the door, as shown. Therod or shaft 18 is pivotally connected to the free end of the pitman-rod16, so that upon movement of said pitman-rod the rod 18 will beoscillated in the bearings formed by the screw-eyes 20.

Between the rod or shaft 18 and the outer edge of the door is arranged asecond v ertically-disposed rod .or shaft 21, the ends of which are bentlaterally at right angles to form crank -arms 22, the ends of which arebent outwardly and engage screw-eyes 23, whereby said shaft 21 ispivotally connected to said door. The crank-arms 22 extend in anopposite direction to the crank-arms 19, which are on the ends of theshaft 18. Mid way between the ends of the shaft 21 the same is bent toform an offset portion 24. This construction is to prevent the shaft 21from striking the hand of a person when opening the door. The shaft 21is pivotally connected to the free end of the pitman-rod 17, wherebyupon movement of the said pitrnan-rod the shaft 21 is oscillated in itsbearings 23.

On the pulley 9 is eccentrically arranged a wrist-pin 25, to which ispivotally secured the upper end of a vertically-disposed rod 26, thelower end of which is offset and adapted to work through a guide-eye 27.To the wrist-pin 25 is also secured one end of a horizontally-disposedrod 28, the opposite end of which is slidably mounted in a guide-eye 29,

which is secured to the door-frame at thetop of the door. By thisarrangement the rods 26 and 28 will be reciprocated in their respectiveguide-eyes as the pulley 9 is rotated. A

()n the rods or shafts 18 and 21 and rods 26 and 28 is adapted to besecured a fringe or brush, which when said shafts are oscillated orreciprocated will agitate said fringe or brush and thereby frighten awayany flies which may be on or near the screen-door.

In operation as the door is opened the cord 7 will be pulled, therebyraising the weight 13 and rotating the pulley 6 and shaft 2 on which thesame is mounted, causing the cranks 14 and 15 to actuate the pitman-rods16 and 17, thereby oscillating the fringed rods 18 and 21. The rod 18 isformed with an offset portion 18 to prevent said shaft 18 frominterfering with the movement of the pitmanrod 17. As the cord? is drawnover the pulley 9 by the opening of said door said pulley will berevolved, thereby causing the eccentrically-arranged wrist-pin 25 toreciprocate the rods 26 and 28, thus agitating the fringeor brushsecured to said rods.

It will be observed that the weight 13 on the end of the cord 7 serves adouble function, one office of said weight beingto create a tension forsaid cord and the other office being to close the screen-door after thesame has been opened. I

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A fly-brush for doors consisting of a main drive-shaft, meansactuated by the opening or closing of said door to rotate saidshaft,cranks formed on the same, cranked rods or shafts pivotally mounted onsaid door, pitman-rods connecting said cranked rods or shafts with thecranks on said drive-shaft whereby the former are oscillated, andfringes or brushes secured to said cranked shafts or rods, substantiallyas described.

2. A flybrush for doors consisting of a main drive-shaft journaled ,onsaid door, a pulley secured to the upper end of said shaft, anoperating-cord secured to the frame or jamb of the door and adapted topass around said pulley and through guide-pulleys on said frame, wherebyupon opening said door said cord will rotate the pulley and thedrive-shaft, vertically-disposed rods or shafts having laterally-bentends forming crank-arms which are pivotally connected to said door toproject in opposite directions, means whereby said cranked rods areoscillated by the rotation of said drive-shaft, and fringes or brushessecured to said rods,substantially as described.

3. A flybrush for doors, consisting of a main drive-shaft journaled onsaid door, a pulley secured to the upper end of said shaft, anoperating-cord secured to the frame or jamb of the door and adapted topass around said pulley and through guide-pulleys on said frame, wherebyupon opening said door said cord will rotate the pulley and thedrive-shaft, a weight secured to the end of said cord to close said doorto keep said cord stretched, vertically disposed cranked rods pivotallymounted to said door, cranks formed in said drive shaft, pitman rodsconnecting said cranks with said cranked rods whereby upon the rotationof said drive-shaft said cranked rods are oscillated, an offset portionformed in said vertical rods and fringes or brushes secured to saidcranked rods, substantially as described.

4. A fly-brush for doors consisting of a main drive-shaft journaled onsaid door, a pulley secured to the upper end of said shaft, anoperating-cord secured to the frame or jamb of the door and adapted topassaround said pulley and through guide-pulleys on said frame, wherebyupon opening said door said cord will rotate the pulley and thedrive-shaft, a weight secured to the end of said cord,vertically-disposed cranked rods pivotally mounted on said door, meansactuated by said driveshaft to oscillate said rods, avertically-disposed rod slidingl y mounted on the door frame or jambadjacent to the outer edge of the door, a horizontally disposed barslidably mounted on the door frame or jamb above said door, a wrist-pineccentrically arranged on one of said guide-pulleys to which one end ofthe said rods are connected,whereby-upon the rotation of saidguide-pulley said rods will be reciprocated, and fringes or brushessecured to said reciprocating and oscillating rods, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit' nesses.
